Application filed April 24, 1924. Serial No. 708,724.

This invention aims to provide an improved socket for a separable fastener.

In the drawings which illustrate a preferred embodiment of my invention,

- Fig. 1 is an elevation view showing the socket attached to a support;

Fig. 2 is a section on the line 2-2 of Fig. 1, being partly'in elevation;

Fig. 3 is a side view partly in section and partly in elevation of the parts of the socket prior to assembly thereof;

Fig. lis a section, partly in elevation, of the socket showing the relation of the parts prior to crimping the prongs over the head of'the attaching screw;

s Fig; 5 is a side elevation of the preferred form of socket; and

. Fig. 6 is a rear elevation of the preferred form of socket.

Referring to the preferred form of my invention, I have shown a flush-type socket including a casing preferably formed from a single sheet of metal. The casing illustrated "includes a body part '1 generally cylindrical in cross section, a flange 2 at the outer end of the casing, a front face 8 preferably dished towards a stud-receiving aperture 4 which is surrounded by a. rounded stud-engaging wall 5 formed by turning inwardly the edges of the front face adjacent the stud-receiving aperture 4:. The front face also presents two generally radial toolreceiving slots 6'6' extending outwardly from the periphery of the stud-receiving aperture. The socket illustrated presents at its inner end a screw 7 having a square head 8 which is secured rigidly to the casing by a plurality of prongs 9 extending from the innermost end of the casing. These prongs overlie the edges of the head 8 of the screw 7 and are clenched against the adjacent face of the head, while the opposite face of the head, adjacent the corners, lies against the flat surfaces 10'1ocated between the prongs 9.

Within the socket I have provided'a sealing disk 11 normally urged into aperture closing position by a spring 12 seated against the inner face of the head 8 of the screw. The sealing disk normally covers the stud receiving aperture 4 andthe tool-receiving slots 66, thereby to exclude dust and dirt from the casing when a stud is not secured thereto, and to contribute to the operation of certain types of studs not described herein.

Assuming the parts of the socket to be un assembled, as illustrated in 8, assembly thereof is in the following order,first the sealing disk 11 is dropped into the casing,

the spring 12 is then dropped into the casing upon the sealing disk, and the head 8 of the attaching screw is then placed, with the corners thereof, beti een the upstanding generally curved prongs 9, by first inserting one corner thereof between two of the prongs and then tipping the other three corners into engagement with the fiat surfaces 10 between the other prongs. As illustrated in-Figs. 3 and at, the prongs 9 are normally slightly curved so that the head of the screw cannot pass by themwithout tipping the screw relative to the casing. Thus the parts are temporarily held in the relation shown in Fig. 4; until a die (not shown) upsets the prongs against the face of the head 8 of the screw and seats the head of the screw on the flat surface 10, as hereinbefore stated. When the socket is assembled, as illustrated in Figs. 5 and 6, there can be no rotation of the casing without corresponding rotation of the attaching screw.

The body 13 of an automobile or like support is first prepared for attachmentof the socket thereto by drilling a socket-receiving recess therein and a relatively small hole concentric therewith into which the screw may be inserted. To attach the socket to the body of the car, I first manually place the socket in'the socket-receiving recess and the screw-receiving hole and then with the use of a screw-driver or other suitable tool blade inserted in the tool-receiving slots 6, (3, I rotate the socket in a clockwise direction. Thus the screw turns into the body 13 and draws the closely fitting body part 1 of the easing into the socket-receiving recess until the flange 2 seats against the outside surface of the automobile body 13.

The socket herein described and illustrated is simple and inexpensive. but presents a neat appearance when secured to an automobile, the only part thereof which ex' tends beyond the outer surface being the flange 2, which, being of greater diameter than the body of the socket, covers the edges of the socket-receiving recess which would otherwise appear unsightly.

While I have shown and described a preferred embodiment of my invention, it will a esa ice be understood that I have done so for purposes of clarification and not for purposes of limitation, my inwntion being best defined in the following; claims.

Claimsi A fastener element including a casing having); a cylindrical inner end portion presenting a plurality of edge seats and a plurality of attaching prongs and an attaching member hayingone end thereof seated against said edge seats and held in fixed relation with said casing by said prongs.

A fastener element including a one" piece casing and an. attaching; screw, said casing presenting at its inner end a plurality of alternating edge seats and projecting); portions and said screw presenting a head portion seated against said edge seats and held thereagainst by said projections to prevent relative rotation between the casing" and the screw.
